Kowa Sporting Optics 15-45x55 PROMINAR Pure Fluorite Straight Spotting Scope
The TSN-554 15-45x is a unique compact spotting scope featuring a fluorite crystal objective lens, designed to make your journeys truly memorable and immersive.
Features

Measuring just a mere 288mm in length and weighing only 800g, this spotting scope is truly compact and makes the perfect travel companion.
Benefits

Wherever your journey takes you, the Kowa spotting scope is the perfect travel companion.
